Bug description:
  [Impact]

  A crash after fix to bug #755842.

  [Test case]

  Use super+W rapidly a few times.

  [Regression Potential]

  Should be low, correct usage of the vector variable. Test wall
  plugin's offset movement functionality in general.

  TESTCASE:

  ctest -D ExperimentalMemCheck
  (this option was only added on 20 June 2012)

  ORIGINAL DESCRIPTION:
  Running compiz 1:0.9.8+bzr3249-0ubuntu1 got a crash in movementWindowOnScreen after doing super+W a few times.

  valgrind says:

  ==3648== Invalid read of size 2
  ==3648==    at 0x806092A: compiz::wall::movementWindowOnScreen(CompRect const&, CompRegion const&) (rect.h:178)
  ==3648==    by 0x44BCEC7: ???
  ==3648==  Address 0x44bd026 is 14 bytes inside a block of size 20 free'd
  ==3648==    at 0x402ACFC: operator delete(void*) (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so)
  ==3648==    by 0x8060965: compiz::wall::movementWindowOnScreen(CompRect const&, CompRegion const&) (new_allocator.h:98)
  ==3648==    by 0x44BCEC7: ???

  The classic case of iterating a temporary vector that goes out of
  scope while iterating. Annoying.
